Investigation on PTO control of a Combined Axisymmetric Buoy-WEC(CAB-WEC) [PDF]

open access: yesOcean Engineering, 2019
The Combined Axisymmetric Buoy (CAB), a vertical axisymmetric buoy, has the potential to deliver a high energy absorption power. Considering the CAB-Wave Energy Converters (WEC), in order to achieve higher efficiency, the Power Take Off (PTO) systems, which converts the float motion into energy output, needs to be properly controlled.

WEC: Weighted Ensemble of Text Classifiers [PDF]

open access: yes2020 IEEE Congress on Evolutionary Computation (CEC), 2020
Text classification is one of the most important tasks in the field of Natural Language Processing. There are many approaches that focus on two main aspects: generating an effective representation; and selecting and refining algorithms to build the classification model.

Economics of WECs [PDF]

open access: yes, 2016
In wave energy, perhaps more so than any other industry, the economics of product development and product ownership are not separate from the product engineering and design. This is the case because, despite high potential of untapped energy resource and the constant attention of academic research and innovative companies and inventors, as yet no one ...

Weighted Effect Coding for Observational Data with wec [PDF]

open access: yesThe R Journal, 2017
Weighted effect coding refers to a specific coding matrix to include factor variables in generalised linear regression models. With weighted effect coding, the effect for each category represents the deviation of that category from the weighted mean (which corresponds to the sample mean).

Contributions to Modeling, Simulation and Controlling of a Pumping System Powered by a Wind Energy Conversion System

open access: yesEnergies, 2021
At present, the energy consumption of the pumping unit represents the highest cost in operating a pumping system. Due to this reason, this paper proposes a reliable and robust solution for integrating a wind energy conversion system (WECS) into an ...
